However, it's now believed that Miz Markle may don another piece from the late philanthropist's jewelry collection. According to royal expert Ingrid Seward, the Suits actress could very likely wear the same tiara Diana wore on her wedding day. She explained to Us Weekly:

"She will have access to jewels from the royal collection made available to her by the Queen. She can choose something suitable, but she might also have the Spencer tiara, which is also Harry's heritage and is the one Diana wore on her wedding day."

That would be such a lovely way to pay tribute to Harry's mother. Seward continued:

"Diana was very proud of her Spencer heritage and I think Harry will like his future bride to carry this tradition on. She will not own the tiara but will have the choice to wear it if she wants to. If not, she will certainly be loaned a tiara on her wedding day. Harry will present her with a necklace or something from his mother's collection."

Makes sense! Still, as an American divorcée, Meghan might modernize her wedding day look and go sans a tiara. Who knows.

Regardless, the 33-year-old royal is passionate about keeping his mother's legacy alive. During the twosome's first TV interview as a couple, Harry said he thought Diana and Meghan would be "thick as thieves" and potentially even "best friends." Excuse us while we go sob into a tissue.

"The ring is — is obviously yellow gold because that's what — her favorite and the main stone itself I sourced from Botswana. The little diamonds either side are from my mother's jewelry collection to make sure that she's with us on this on this crazy journey together."

We honestly couldn't be happier for these two. We're wishing them only the best during this exciting time!!
